At the same time the Gallery takes care of a fund of monuments, public carvings, plaques and fountains on the outdoors of Prague including theirs restoration and placing of new ones. Since the beginning the professionals of the Gallery have the goal to build up a collection of Czech art of the 19th and 20th century and to introduce it to public on a professional level.

Shortly after its foundation the Gallery made permanently accessible an important collection of sculptures, paintings and graphics of František Bílek. In 1994 a permanent exposition of the works of this artist was opened in his natal home in Chýnov at Tábor in addition to Bílek´s Prague atelier and villa, where his work is to be exhibited again since September 1, 2010 after an ambitious reconstruction is finished.

Another artistic and historic building and at the same time a specific exhibition space in care of the City Gallery Prague is the baroque castle Troja with a French garden, an orchard and an orangery, all belonging to the most important examples of the baroque architecture in Bohemia.

Since 1988 extensive space demanding expositions are organized in gothic Dům U Kamenného zvonu (The Stone Bell) on Staroměstské náměstí (Old Town Square) and since 1994 also the exhibition halls of the Gallery in the Městská knihovna (Municipal Library) originally built for this purpose accommodate them.

The halls on the second floor of the Staroměstská radnice (Old Town Hall) are dedicated to the line of experimental exhibitions as well as already traditionally to the art of the youngest generation.

Since the second half of the ninetieths the historic Dům U Zlatého prstenu (The Golden Ring) in the old town Ungelt became another original exhibition building. This renovated space will be enliven by a new long term exhibition After Velvet, that introduces the Czech art from 1989 till present by way of the work of several artistic generations.

Today, in 48 years of its existence, the Gallery owns 14,522 of artistic pieces of work. The Gallery also takes care of more than 400 artifacts connected with public carvings, namely 208 Prague installed public carvings registered with the Formation Deed of the Gallery. Its art historians together with professionals from other institutions made available important topics, phenomenon and personalities of the history of Czech art and they did so in international context; up to now it was more than 650 exhibitions.
